Setting up headless Raspberry Pi OS on macOS

1. README.md

I recommend starting with Stretch for development projects. Stretch Lite doesn't include the build tools that most projects require. It's easier to just start with them in place rather than spend a lot of time installing things.

Download the latest Raspbian image from https://www.raspberrypi.org/downloads/raspbian/.

Insert your SD card and determine where it's mounted.

diskutil list

Find the one that matches your SD card and unmount it.

diskutil unmountDisk [path to disk, e.g. "/dev/disk2"]

Burn the image to your SD card. This can take several minutes.

sudo dd bs=1m if=[path to img file, e.g. "2017-08-16-raspbian-stretch.img"] of=[path to rdisk, e.g. "/dev/rdisk2"] conv=sync

Ensure the disk is mounted again, then enable SSH.

touch /Volumes/boot/ssh
touch /Volumes/boot/wpa_supplicant.conf

Eject your SD card.

diskutil eject [path to disk]

Connect the Raspberry Pi to your Mac via an ethernet cable and turn on internet sharing to ethernet.

Copy your public SSH key the the Pi.

cat ~/.ssh/id_rsa.pub | ssh [email protected] "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys"
# From https://www.digitalocean.com/community/tutorials/how-to-configure-ssh-key-based-authentication-on-a-linux-server

Then set up basic configuration.

ssh [email protected]

sudo raspi-config

2. WiFi.md

Using Edimax EW-7811Un (rtl8188cus chipset) OR built-in WiFi on Raspberry Pi 3

Edit /etc/wpa_supplicant/wpa_supplicant.conf to match the following.

country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
	ssid="[SSID]"
	psk="[password]"
}

3. ES9023-setup.sh

Modified from https://www.hifiberry.com/guides/configuring-linux-3-18-x/.

# Configure device tree overlay file
# To do this, you must edit /boot/config.txt and add the following line

dtoverlay=hifiberry-dac

#Configure ALSA
#Create /etc/asound.conf with the following content:

pcm.softvol {
	type softvol
	slave.pcm "plughw:1"
	control {
		name "Master"
		card 0
	}
}

# Reboot

# Make sure device shows up:
aplay -l
# Look for "card { id }: sndrpihifiberry"

# Initialize mixer
speaker-test -D softvol -c 2 -t wav

4. shairport-sync.md

Set shairport-sync to use the hifiberry-dac

sudo nano /etc/shairport-sync.conf Change this:

alsa = { output_device = "hw:1"; (or whatever number card "sndrpihifiberry" is above) interpolation = "soxr"; }

If audio is underflowing, set audio_backend_buffer_desired_length to 22050

Change any other settings you want (name, metadata on, etc.)

Restart Shairport-sync

sudo service shairport-sync restart

5. spotify-connect.sh

# In /usr/lib/, add one of these libraries (Use the armv6 ones for Rpi1, armv7 for Rpi2/3) https://github.com/sashahilton00/spotify-connect-resources/tree/master/libs

# Run this before Install section of spotify-connect-web

```sh
sudo apt-get install python-pip python-gevent python-alsaaudio
```

# Add this to /etc/shairport-sync.conf
sessioncontrol = {
  run_this_before_play_begins = "/home/pi/stop_spotify_connect.sh";
  run_this_after_play_ends = "/home/pi/start_spotify_connect.sh";
  wait_for_completion = "yes";
};

```sh
chmod +x /home/pi/start_spotify_connect.sh
chmod +x /home/pi/stop_spotify_connect.sh
```

start_spotify_connect.sh

#!/bin/bash

LD_LIBRARY_PATH=/home/pi/spotify-connect-web python /home/pi/spotify-connect-web/main.py -u [username] -p [password] -k /home/pi/spotify_appkey.key -n [name] -b 320 --playback_device softvol --mixer Master &

stop_spotify_connect.sh

#!/bin/bash

pgrep -f spotify-connect-web/main.py | xargs kill -9

Awesome, thanks for sharing :)

Glad you found it useful!

Thank you so much for this!

Really great. Thank you! Made the set up so quick and easy!

I followed every steps, but cannot ssh to [email protected] because it asks for password. Tried raspberry but didn't work.

Thanks for pointing this out @theoctober19th. In the latest version of Raspberry Pi OS (2022-04-04), the "pi" user has been removed. I've just updated the section about writing the image with instructions on how to create the "pi" user.

Thanks @celeryclub for making setup for easy:)
